A new version of the Troika RPG is up on Kickstarter. The game is designed to be rules-light, so even if you've never played an RPG before, there's no huge lists of charts or tables you have to consult. They've even given you a set of backgrounds that your character can have, and reading over them will give you a good idea of what sort of things your character is capable of, as well as the universe overall.

From the campaign:

Troika! is a rules-lite beginner-friendly science-fantasy role-playing game for 2+ people written in the tradition of 80s British RPGs. Players can be up and running in a matter of minutes with any of the 36 randomly assigned character backgrounds, each containing everything they need to know to get into the tone and cadence of the world. Before long, the party will be travelling from sphere to crystal sphere across the humpbacked sky, not lost, but moving towards adventure.

The Kickstarter is closing in on 2x funded with still 14 days left to go.
